　　美国留学化学工程专业个人陈述取胜在于朴实无华

　　Sample PS_ Chemical Engineering

　　Personal Statement

　　I am enchanted with chemistry; whenever I see the various and complex chemical reactions at the molecular level, I feel that I have entered a brand new world.

　　It was in my senior year of high school that I came in contact with chemistry courses. When the chemistry teacher demonstrated the synthesis process of polyethylene through the computer, I saw that the ethylene monomer model opened the double bonds and connected together under the reaction conditions and catalyst, so that double bonds, open chains, chaining, and other processes, which had been obscure and abstract previously, suddenly became detailed and clear. Later I found that the polymers were widely used in daily life, ranging from the plastic cups to making artificial bones and hearts, along with other advanced scientific products. In further studies I came to know that the exploration for inorganic matter had reached a certain limit, yet there was still much unexplored, especially high polymers. Therore, without hesitation, I selected chemistry for my major at the Chemical Engineering and Technology Department of XX University.

　　I was excited to be able to learn my beloved subject, so in the past four years I took full advantage of all the chances to learn practical operation and application related to chemistry. In my junior year I took part in the chemical engineering course design, which was to design the packing rectifying tower. The design involved extensive knowledge relating to packing tower, including the option of packing, calculation of the technical size of the packing tower calculation of packing layer drop, selection and arrangement of the packing tower internals, and so on. One difficulty in the design was the selection of one of the packing tower internal components: the liquid distribution device. I selected the slotted liquid distributor after much research in the library. Such design solved the problems of the uneven gas-liquid distribution and resistance, which appeared in traditional similar packing towers. When I brought my design scheme to my teacher, I received a positive evaluation. My design and self-study were greatly improved through this design, which also increased my confidence in the field of chemistry field.

　　Due to my excellent performance, I was selected for the chemical research group in my senior year, becoming the only undergraduate in the group. I studied mPEG, poly (SA, LA), and mPEG triblock co-polymer. I took part in the core part of the project: preparation of sebacic acid anhydride prepolymer, preparation of sebacic acid-D,L lactic acid prepolymer, synthesis of the ultimate target product, and measured the drug release of the obtained products. The project enabled me to grasp more complicated experiment operations, and gave me a clear and complete understanding for the professional field. Furthermore, it enabled me to possess the required qualities of a good chemist, gaining knowledge in the research method, research process, test design, and planning. In the end I realized that what I learned in the application of biology has a very promising development, not only because it is full of infinite possibilities, but it can also benit humankind.

　　There was still a big gap between China and the United States with respects to materials of the macromolecule field. So for my future studies, I am most interested in two aspects. The first is the development of environment-friendly materials. Because of its high costs in China, environmental-friendly materials are not used much. I hope to not only find new environment-friendly materials, but also lower its cost and increase its production. The second direction I am interested in is the study of polymeric biomedical materials. I think that many incurable diseases can be cured with the development of medical technology in combination with polymer materials. Therore, I also hope my future overlaps the two fields: chemistry and medicine.

　　The United States is leading in the field of polymer materials. So it is my dream to have my graduate studies in America. After comparing similar graduate projects offered by various universities, I selected your university because I think that both the teaching and research aspects in regards to my two focus directions are the best. I believe the education of your university will be able to meet my desire for research and knowledge. Besides this, your university has an excellent reputation, high quality faculty, advanced teaching equipment, rich campus activities, and numerous outstanding alumni.

　　After I graduate I plan to come back to China and work for a chemical company, for example GE, where I hope to take part in the study of polymeric membrane used in the water treatment process, or perhaps Johnson & Johnson, where I hope to conduct research on polymer materials of artificial organs. My long-term goal is to be able to establish my own research lab. I hope what I learn can benit more people.

　　点评：

　　申请者本身是国内某大学的化学工程与工艺专业的本科生。GPA3.2，专业基础知识比较扎实，但是和很多重视理论学习的学生一样，她所参加的项目都不是很特别高精尖。但是，理工科的项目却很重视申请者曾经的项目经历。所以，如何帮助申请者遮盖短处甚至把短处变成长处成为了PS写作中必须要完成的任务。

　　文章的第一段和第二段写了申请者对化学的兴趣和选择化学工程这个专业的原因。通过追忆中学时代对化学的喜爱表现了对此专业兴趣的持久性。第三段，第四段是文章的重点，这两段写了申请者在大学期间做过的研究/项目和取得的成绩。在叙述中，并没有过多的介绍项目的细节或者夸大甚至虚构项目本身的含金量而是着重突出了申请者爱钻研，能解决问题，动手能力强的特点。因为这些特点是一个工程师必须的宝贵素养也是被很多高端申请者忽略的地方。所以可以说这两段很好的完成了提升申请者的任务。第五段的精彩之处在于写到了申请者发现的中国在高分子研究领域的问题，并有针对性的列出了申请者希望在未来学习中从事的研究方向和具体的原因。具体的谈到自己的学术兴趣和感兴趣的研究领域是研究生申请PS中必须要写到的，这样可以很好的让学校客观的判断申请者十分适合所申请的项目。

　　最后一段，谈到了对未来的详细规划, 短期和长期的目标。目标写的很细化也很实际。能够感到申请者对该行业的了解和对职业生涯有名确的规划。

　　整体来看，这篇PS充分展示了学生的优势，回避了缺陷，而且语言比较朴实，没有自吹自擂的内容，读后让人觉得申请者是理工科研究生项目很有竞争力的候选人。
